Set click-through URLs
Under "Creative events," view the click tags table.
Each click tag here corresponds to an exit in your creative. The URLs for these click tags are used for the creative in every ad. However, you can disable them and use URLs at the ad level instead.
If you want to use these URLs: Enter them here. If you see "Uses ad-level click-through URL," that means the URL is disabled. To enable it, click the field and uncheck the "Uses ad-level click-through URL" box. This will enable the URL so that it can be used for all assigned ads.
If you want to use different URLs for each ad: Disable the URLs here and set them in each ad. To disable a URL, click it and check the "Uses ad-level click-through URL" box. Then set your URLs for each ad under "Creative assignments," in the Landing page column.
